Graphic card performance impact on baking light
10k sampling is a very bad idea, you will have to use a lower value and find the sweet spot for your render. A RTX graphics card could be used for denoising with OptiX, it's build into blender. But do not sample with 10k, the best RTX card won't be able to render magically in some minutes with this sampling value.
